CUT-OFF DEVICE FOR TRAIN-LINES.

SPECIFICATION forming part of Letters Patent No. 706,433, dated August 5, 1902. Application filed March 17, 1902. Serial No. 98,585. (No model.)

To 0% whom it may concern:

Be it known that I, GILBERT C(Moonn, a citizen of the United States, residing at Guntown, in the county of Lee and State of Mississippi, have invented new and useful Improvements in Cut-Off Devices for Train- Lines, of which the following is a specifica tion.

My invention relates to cut-0E devices for train-lines; and the object of the same is to construct a device which will be automatically operated by the pulling apart of a train to cut ofi the escape of air from the trainJine,

The novel construction used by me in carrying out my invention is fully described in this specification and claimed, andillustrated i a hose-pipe 4. Mounted in the opposed ends 5 of the train-line 3 are two-way cocks 6, having stems 7, on which are rigidly secured levers 8. The levers 8 are set to extend parallel to the line of draft when the cocks 6 are closed and at right angles thereto when they are avoided.

and 18 are engaged in pairs and the levers 8 are set at right angles to the train-line. If

"the cars should now pull apart, the chains 9 and 12 would become taut and the levers 8 straightened out, thereby closing the valves 6. As the strain increased the head 14 of the snap would be pulled through the jaws 11 and the breaking of the chains 9 and 12 The jaws 11 of the snaps 10 should bestifi enoughto retain their hold on the snap 13 until the levers 8 have been straight ened out. p

I do not wish to be limited. asto detailsof construction, as these may be modified in many particulars without departing from the spirit of my invention.

Havingthus described my invention, what I claim as new, and wish to secure by Letters Patent, is

The combination with a train-line, of a twoway cock mounted in said line and provided with a lever extending at an angle to the said train-line when the valve is open, a chain connected to said lever and bearing a snap-hook, and a chain bearing a snap engaging said first-mentioned snap and having grasping resilient jaws constructed to hold said snap until said lever is straightened out and to release said snapwhen the pull becomes greater andthereby avoid breaking the chains, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- DESSOS.
